NOTE LEROY-SOMER reserves the right to modify the characteristics of its products at any time in order to incorporate the latest technological developments. The information contained in this document may therefore be changed without notice. LEROY-SOMER gives no contractual guarantee whatsoever concerning the information published in this document and cannot be held responsible for any errors it may contain, nor for any damage resulting from its use. CAUTION For reasons of safety of both people and equipment, LEROY-SOMER prohibits use of the DIGISTART STV 2313 for hoisting applications. For the user's own safety, this electronic starter must be connected to an approved earth ( terminal). If accidentally starting the installation is likely to cause a risk to personnel or the machines being driven, it is essential to supply the equipment via an isolating device and a circuitbreaking device (power contactor) which can be controlled via an external safety system (emergency stop, detection of errors on the installation). The electronic starter is fitted with safety devices which, in the event of a fault, control stopping and thus stop the motor. The motor itself can become jammed for mechanical reasons. Voltage fluctuations, and in particular power cuts, may also cause the motor to stop. The removal of the causes of the shutdown can lead to restarting, which may be dangerous for certain machines or installations. In such cases, it is essential that the user takes appropriate precautions against the motor restarting after an unscheduled stop. The electronic starter is designed to be integrated in an installation or an electrical machine. It is therefore the responsibility of the user to take all necessary precautions to ensure that the system complies with current standards. LEROY-SOMER declines all responsibility in the event of the above recommendations not being observed.... 2
SAFETY AND OPERATING INSTRUCTIONS FOR ELECTRONIC STARTERS (in accordance with the low voltage directive 73/23/EEC modified by 93/68/EEC) Throughout the manual this symbol warns of consequences which may arise from inappropriate use of the starter, since electrical risks may lead to material or physical damage as well as constituting a fire hazard. 1 - General Depending on their degree of protection, electronic starters may contain unprotected live parts, which may be moving or rotating, as well as hot surfaces, during operation. Unjustified removal of protection, incorrect use, faulty installation or inappropriate operation could represent a serious risk to people and equipment. For further information, consult the manual. All work relating to transportation, installation, commissioning and maintenance must be performed by experienced, qualified personnel (see IEC 364 or CENELEC HD 384, or DIN VDE 0100 and national specifications for installation and accident prevention). In these basic safety instructions, qualified personnel means persons competent to install, assemble, commission and operate the product and possessing the relevant qualifications. 2 - Use Electronic starters are components designed for integration in installations or electrical machines. When integrated in a machine, commissioning must not take place until it has been verified that the machine conforms with Directive 89/392/EEC (machinery directive). It is also necessary to comply with standard EN 60204, which stipulates in particular that electrical actuators (which include electronic starters) cannot be considered as circuitbreaking devices and certainly not as isolating switches. Commissioning can take place only if the requirements of the Electromagnetic Compatibility Directive (89/336/EEC, modified by 92/31/EEC) are met. The electronic starters meet the requirements of the Low Voltage Directive 73/23/EEC, modified by 93/68/EEC. The harmonised standards of the DIN VDE 0160 series in connection with standard VDE 0660, part 500 and EN 60146/VDE 0558 are also applicable. The technical characteristics and instructions concerning the connection conditions specified on the nameplate and in the documentation provided must be observed without fail. 3 - Transport, storage All instructions concerning transportation, storage and correct handling must be observed. The climatic conditions specified in the technical manual must be observed. 3
4 - Installation The installation and cooling of equipment must comply with the specifications in the manual supplied with the product. Electronic starters must be protected against any excessive stress. In particular, there must be no damage to parts and/or modification of the clearance between components during transportation and handling. Avoid touching the electronic components and contact parts. Electronic starters contain parts which are sensitive to electrostatic stresses and may be easily damaged if handled incorrectly. Electrical components must not be exposed to mechanical damage or destruction (risks to health!). 5 - Electrical connection When work is performed on electronic starters which are powered up, national accident prevention regulations must be respected. The electrical installation must comply with the relevant specifications (for example conductor cross-sections, protection via fused circuit-breaker, connection of protective conductor). More detailed information is given in the manual. Instructions for an installation which meets the requirements for electromagnetic compatibility, such as shielding, earthing, presence of filters and correct insertion of cables and conductors, appear in the documentation supplied with the electronic starters. These instructions must be followed in all cases, even if the electronic starter carries the CE mark. Adherence to the limits given in the EMC legislation is the responsibility of the manufacturer of the installation or the machine. 6 - Operation Installations in which electronic starters are to be integrated must be fitted with additional protection and monitoring devices as laid down in the current relevant safety regulations, such as the law on technical equipment, accident prevention specifications, etc. Modifications to electronic starters using control software are permitted. Active parts of the device and live power connections must not be touched immediately after the electronic starter is powered down, as the capacitors may still be charged. In view of this, the warnings fixed to the electronic starters must be observed. During operation, all doors and protective devices must be kept closed. 7 - Servicing and maintenance Refer to the manufacturer's documentation. This manual is to be given to the end user. 4

MODBUS network interface MODBUS network @ / DATA DIGISTART STV 2313 Read Parameter setting Start/Stop CDC - START 7.28 -: no ANLG REF :o ffs I? MODE RUN Read Start/Stop ES-START Mem STOP RESET Read Parameter setting Start/Stop 1.1.1 - Reminder of MODBUS protocol The main characteristics of a Modbus network are as follows : - Master slave network. - Half duplex transmission (they each take turns to send). - Modbus does not require any particular transmission medium, but is very often used with a RS 485 link. - Topology : network organised as a bus. - Theoretical number of subscribers : 247. This number can be limited to 32 by the RS 485 link, as in this example. - Line protocol : ASCII or RTU transmission. Digistart uses RTU mode because it is more commonly used and more reliable. - Line access protocol : Question and answer mechanism between a master and a slave, or broadcasting of a request from the master to all the slaves. 6
1.1.2 - Transmission in RTU mode Frames transmitted in RTU mode have no header, nor end delimiter. Frame synchronisation is performed by simulating a synchronous message : the receiving station controls the time which elapses between the receipt of two consecutive characters; a silence corresponding to the time required for transmission of three and a half characters, which does not correspond to the end of a frame, implies that the next character received will be the first field of a new frame. The partial frame thus received is said to be physically incorrect, it will not prompt an answer frame, and will be overwritten by the next frame received. Each byte of information in an RTU frame is coded in hexadecimal (0 to FF). A control key is integrated in the frames, which consists of two bytes arising from the calculation of a CRC16 (16-bit Cyclic Redundancy Check) x16 + x15 + x2 + 1, applied to the whole content of the frame, except the control field. Both bytes are transmitted with the LSB first. RTU coding is mainly used by MODBUS network applications, especially for high transmission error overlap permitted by use of the CRC16. 1.1.3 - Software interface To communicate with the DIGISTART over the network, simply write data to the usual DIGISTART addresses or read them using MODBUS protocol read and write commands. When a write command is sent to the DIGISTART, the interface checks that no error has been introduced into the message using a calculation which checks the value of each byte (CRC16). The result of this calculation is part of the message sent by the master, which allows the DIGISTART to compare the calculation received with the calculation performed locally. If the check is OK, the DIGISTART sends an acknowledgement message to signal to the master PLC that the command has been received. If the message received by the DIGISTART is incorrect, no acknowledgement is sent and the PLC should send back the same command. When a read command is sent, the DIGISTART sends the answer as the acknowledgement message. Start, stop or reset commands are written to a particular address. 7

If it has, make a claim against the transporter. 2.2 - Installation precautions It is essential to protect the module power supply with 2 GI 3.15A fuses. - Keep the COM - START module away from any radiation source (transformer, busbars, etc). - Do not run the COM - START module cables alongside the power cables. 10
3 - COMMISSIONING The level of performance obtained depends on the parameter setting. Inappropriate settings can have serious consequences for personnel and the machine itself. The STV 2313 parameters should be set by experienced qualified personnel. 3.1 - Presentation Parameter setting : The slide switch in this position signifies that the parameters are being set (entry or modification) for the COM - START network option only. Communication : The slide switch in this position signifies that the COM - START network option is being used as a communication interface for the DIGISTART. CDC - START : Female 9-pin SUB-D socket for connection to the CDC - START console (essential for setting the COM - START parameters). STV 2313 : Male 9-pin SUB-D socket for connection to the DIGISTART starter (STV 2313 only). Network In : Female 9-pin SUB-D socket for connection to the external network (IN). Network Out : Female 9-pin SUB-D socket for connection to the external network (OUT). 3.2 - Setting COM - START parameters Position the slide switch on "Parameter setting" using the specially provided plastic screwdriver, then switch on the DIGISTART and the COM - START network option. Using the CDC - START console, go to the "MODBUS initialisation" menu using the appropriate arrows. Carefully define each of the required parameters, not forgetting to store the selections made (see Parameter setting table on the next page).

The first 5 sub-sections of the table opposite show the link which should be established. "MODBUS monitoring" is used to define the frequency of the test on the serial link when in STV communication mode. "Launch self-test" is used to ensure that the COM - START option card is not faulty. This self-test should only be launched after disconnection of the network links. "Place in MODBUS" is used to define the line termination required depending on the wiring characteristics of the COM - START option. There are in fact several connection possibilities, especially where the number of wires is concerned. "STV parameter setting by" and "STV control by" are used to define the interfaces selected for these operations. An EEPROM in COM - START allows the chosen selections to be stored. IMPORTANT : Do not forget to program the DIGISTART, especially the selection "Control via the terminal block or via the keypad". To authorise "Control via MODBUS", you should first select "Control via the keypad" for the DIGISTART. If the slide switch remains in this position (Param.) without any activity for 5 minutes then the CDC - START changes to Read mode and indicates the COM - START software version on the first line, and the result of the self-test (updated on each launch) on the second line. When the COM - START parameters have all been set, change the slide switch to the "Communication" position. 3.3 - Using COM - START 3.3.1 - Read mode All the DIGISTART parameters which can be accessed via the serial link can be read. These include : all the parameter values (current, voltage, power, etc), the DIGISTART status (starting phase, operation, etc), any faults which have occurred (motor thermal, overload, underload, etc) and the DIGISTART characteristics (software version, rating, etc). This type of information is usually available on CDC - START. 3.3.2 - Parameter-setting mode It is possible to program all the accessible DIGISTART parameters (including the RV - START, ES - START, FR - START options) with the same precision as when using the CDC - START console. The table of accessible parameters is given in an appendix with the corresponding addresses. If the "Control via MODBUS" function is selected, note the particular features of the "start", "stop" and "reset" sequences outlined below. "Start" sequence : activating the DIGISTART. Can only be performed in two frames, one for setting the bit corresponding to the required command in the appropriate address to 1 and one for resetting it to 0 (similar to a run command during jogging). The "reset" and "stop" sequences are identical to the "start" sequence except that the corresponding bit is different, although it is common to "stop" and "reset". 13

3.4.12 - Special parameters COM - START can be used to return to the DIGISTART factory settings (see STV 2313 manual). This action is performed by writing 1 at the address "1796". COM - START can be used to control the DIGISTART if this option has been selected when setting the COM - START parameters. The address to be taken into account for pilot control of the STV 2313 is 1797 (min. value "0", max. value "255"). The starting sequence described in section 3.3.2 consists of writing 251 at address 1797 followed by 255 at the same address (1797). The stop or reset sequence is performed by initially writing 247 at address 1797 followed by 255 at the same address (1797). 3.4.13 - Read mode The table below lists the different parameters which can be accessed in read mode by the COM - START option, with their addresses and the minimum and maximum values, and also the units.
